ANTENNA STRUCTURE FOR EXCHANGING WIRELESS SIGNALS
First Claim
1. A communication device, comprising:
- a dielectric antenna including an antenna lens that operates as an aperture of the dielectric antenna, the antenna lens having a convex structure that adjusts a propagation of electromagnetic waves in the dielectric antenna to reduce phase differences in near-field wireless signals generated by the dielectric antenna;
a cable comprising a dielectric core coupled to a feed point of the dielectric antenna; and
a transmitter, coupled to the cable, the transmitter facilitates a transmission of the electromagnetic waves, and the electromagnetic waves are guided by the dielectric core to the feed point of the dielectric antenna without an electrical return path.

Abstract
Aspects of the subject disclosure may include, for example, an antenna structure that includes a feed point that facilitates coupling to a dielectric core that supplies electromagnetic waves to the feed point, and a dielectric antenna coupled to the feed point for receiving the electromagnetic waves, the dielectric antenna including an antenna lens that operates as an aperture of the dielectric antenna, the antenna lens having a structure that adjusts a propagation of the electromagnetic waves in the dielectric antenna to reduce a cross section of far-field wireless signals generated by the dielectric antenna. Other embodiments are disclosed.
